Interstate 495 in Delaware


Interstate 495 within Delaware is a 11.47-mile auxiliary of Interstate 95 and bypass of downtown Wilmington.  Interstate 495 opened during 1977 and between 1978-1980 briefly served as mainline Interstate 95 while the South Wilmington Viaduct was being reconstructed.  Interstate 495 in addition to bypassing downtown Wilmington serves as access to the Port of Wilmington.  


Part 1; the history of Interstate 495

During 1948 the Wilmington Transportation Study proposed two limited access corridors to connect from Wilmington to the Pennsylvania State Line.  The first corridor would have followed what is now Interstate 95 (Plan A) whereas the second followed what is now modern Interstate 495 (Plan B) as a bypass of Wilmington.  By 1950 Plan A was selected as a limited access corridor from downtown Wilmington to the Pennsylvania State Line.  

On June 29th, 1956, the Federal Highway Aid Act of 1956 was signed into law on the Federal Level.  The Federal Highway Aid Act of 1956 was the genesis point of the Interstate Highway System and established the corridor of Federal Aid-Interstate #3.  Federal Aid-Interstate #3 would go through the process of design during 1960 and be assigned the designation of Interstate 495 during 1962.  

Construction of Interstate 495 would commence during 1968.  The Christina River Bridge would be completed by 1975 and first completed segment of Interstate 495 between US Route 13 to Interstate 95 in Claymont would open during 1976.  During June 1977 the remainder of Interstate 495 would open to traffic. 

On June 28, 1978, the AASHTO approved realigning Interstate 95 onto Interstate 495.  Existing Interstate 95 through Wilmington was requested to be designated as Interstate 595.  The justification for moving Interstate 95 to Interstate 495 was the higher capacity of the then new freeway bypass which had been completed during 1977.  A secondary justification is noted to be the reconstruction of Interstate 95 through Wilmington.  The designation of existing Interstate 95 through Wilmington as Interstate 595 was deferred by the AASHTO in favor of designating a suggested even numbered three-digit Interstate. 








What had been Interstate 95 through Wilmington was approved to be signed as Interstate 195 and Interstate 395 by the AASHTO on October 27, 1978.  Interstate 395 was to be designated from US Route 202 in Wilmington to what had been the Interstate 495 interchange near the Pennsylvania State Line.  Interstate 195 was to be designated from what was the southern Interstate 495 interchange to Delaware Route 141 in Wilmington.  





Interstate 195 and Interstate 395 through Wilmington were approved by the AASHTO to be renumbered to Interstate 895 on June 26, 1979.  








Interstate 95 was redesignated along the corridor of Interstate 895 by the AASHTO on November 15, 1980.  Likewise, the corridor Interstate 495 was restored to what had been briefly designated as Interstate 95.  The justification for restoring the corridor of Interstate 95 was that the project through Wilmington had been completed. 





During June 2014 the Christina River Bridge on Interstate 495 was closed for emergency repairs after tilting support columns were discovered.  The southbound lanes of Interstate 495 would reopen on July 31st whereas the northbound lanes would reopen on August 23th.  


Part 2; a drive on Interstate 495

South of Wilmington, Interstate 495 splits from northbound Interstate 95 via a right-hand transition.  Traffic headed to Philadelphia and the Port of Wilmington are directed onto Interstate 495. 




Traffic on Interstate 495 northbound is advised the Port of Wilmington is 2 miles away whereas Philadelphia is 30 miles.  Interstate 495 is named the Vietnam Veterans Memorial Highway. 


Interstate 495 northbound Exit 1 accesses US Route 13 Business in Wilmington. 



Interstate 495 northbound Exit 2 accesses Delaware Route 9A and the Port of Wilmington.  



Interstate 495 northbound crosses the Christina River Bridge and accesses 12th Street at Exit 3.  





Northbound Interstate 495 Exit 4 accesses Delaware Route 3 and US Route 13 in Edgemoor.




Interstate 495 northbound follows the shore of the Delaware River to Exit 5/US Route 13 in Claymont.  Interstate 495 terminates at Interstate 95 in Claymont approaching the Pennsylvania State Line.

Trimmer Springs Road (Fresno County)

Trimmer Springs Road is an approximately forty-mile rural highway located in Fresno County.  The corridor begins near in California State Route 180 in Centerville and extends to Blackrock Road at the Kings River in the Sierra Nevada range near the Pacific Gas & Electric Company town of Balch Camp. The roadway is named after the former Trimmer Springs Resort and was originally constructed to facilitate access to the Sanger Log Flume.  Trimmer Springs Road was heavily modified and elongated after construction of Pine Flat Dam broke ground in 1947.   Part 1; the history of Trimmer Springs Road Much of the original alignment of Trimmer Springs Road was constructed to facilitate access to the Sanger Log Flume.   The  Kings River Lumber Company  had been established in 1888 in the form of a 30,000-acre purchase of forest lands in Converse Basin.  This purchase lied immediately west of Grant Grove and came to be known as "Millwood."  The co...

When was Ventura Avenue east of downtown Fresno renamed to Kings Canyon Road? (California State Route 180)

California State Route 180 was one of the original Sign State Routes designated in August 1934.  The highway east of Fresno originally utilized what was Ventura Avenue and Dunlap Road to reach what was then General Grant National Park.  By late year 1939 the highway was extended through the Kings River Canyon to Cedar Grove.   In 1940 General Grant National Park would be expanded and rebranded as Kings Canyon National Park.  The Kings Canyon Road designation first appeared in publications circa 1941 when the California State Route 180 bypass of Dunlap was completed.  Kings Canyon Road ultimately would replace the designation of Dunlap Road from Dunlap to Centerville and Ventura Avenue west to 1st Street in Fresno.   The Kings Canyon Road would remain largely intact until March 2023 when the Fresno Council designated Cesar Chavez Boulevard.  Cesar Chavez Boulevard was designated over a ten-mile corridor over what was Kings Canyon Road, remaini...

Interstate 99 at 30

When it comes to the entirety of the Interstate Highway System, Interstate 99, when fully completed, is nothing more than 161 miles of a roughly 48,000-mile system (0.3% of total length).  Yet, to more than just a handful of people, the number '99' rubs them the wrong way. Interstate 99 follows the path of two US Highway Routes - US 220 from the Pennsylvania Turnpike in Bedford north to Interstate 80 and then to US 15/Interstate 180 in Williamsport.  It then follows US 15 from Williamsport north to Interstate 86 in Corning, New York. Interstate 99 runs with US 220 through much of Central Pennsylvania. (Doug Kerr) US 220 from Cumberland, Maryland to Interstate 80 and US 15 north of Williamsport were designated part of the Appalachian Highway System in 1965.  Construction to upgrade both corridors progressed steadily but slowly.  In 1991, the two corridors were included as a National High Priority Corridor.  The route from Cumberland to Corning consisted of High P...
